PM's

[Citric]

Hi for some reson i am having a problem with my PM's. I sent a PM to another user today, and whilst almost about to send another to a different user. I noticed that my PM box no longer noticed me as Citric, but was now viewing me as Citric1. I looked in the sent and recieved boxes and none of the topics were mine. When i go back in screens lets say to the forum home page it then sees me as Citric, WHAT IS GOING ON?
Can you guys please fix it, and let me know why it is happening? I dont know if this is the first time this has happened, i dont ever know why i looked at the top RHS box that displays our logged in status and name on this ocassion.
